Post subject:  EM Drive recent developments

The controversial EM Drive has been tested in vacuum for the first time, and positive results have been reported: ... -em-drive/

Previous tests weren't done in a vacuum, which meant that convection effects couldn't be ruled out.
The vacuum test however would appear to silence this objection.
The EM Drive is a "propellant-less" thruster. There is no firm consensus on how it seems to be producing thrust, with recent interferometer and speed-of-light measurements even suggesting a "spacetime warp" is being created. However some engineers on the forums have cautioned that this might be due to imprecise measurements.

Hopefully this will turn out better than "cold fusion"...
